The KOBOLD flow meter model DRB is used for measuring and monitoring liquids. The device works according the well-known blade wheel prin- ciple. The four vane blade wheel is retained radially in a highquality sap- phire bearing. The sensor is supplied ready-to-install with pipe fittings or with weld-on sleeves.
The blade wheel is set in motion by the flowing medium. Magnets are embedded hermetically sealed in the ends of the blade wheels. The magnets generate electrical pulses in a Hall-effect sensor mounted out- side the flow area. Various electron- ics units can be used to display and monitor the volumetric flow.
